摘　　要：大型薄壁设备在吊装过程中常采用轴式吊耳。依据标准选择的筒体壁厚往往很大,为了降低成本,考虑在吊耳处设置加厚段,但加厚段的壁厚也远大于依据内、外压计算所得的壁厚,与薄壁设备本身的壁厚相差太大。通过WRC107计算及有限元分析两种方法对某大型薄壁设备非标轴式吊耳处筒体局部应力进行计算,对比两种分析方法的评定法则。结果表明所设计的非标吊耳处应力强度是安全的。为大型薄壁设备非标轴式吊耳的设计提供依据。Large thin-wall equipments often use axial lugs in hoisting process. The wall thickness given by standard is often too big, so setting a thickened section at the lugs can reduce costs, but the thickness of thickened section is also much larger than which calculated based on internal and external pressure and has much difference with the thickness of itself. In this paper, two methods WRC107 and finite element analysis were used to calculate the local stress of non-standard axial lugs, and assessment principles of the two methods were compared. The results show that the stress strength of the non-standard lugs is safe, which can provide the basis for the design of non-standard axial lugs for large thin-wall equipment.
